1. Simultaneous Topology and Material Optimization of Composite Structures under Uncertainty
Abstract : Composite materials are known to have superior stiffness and strength properties per unit weight compared to metallic materials. These properties and the ability to tailor the mechanical properties of composites is the main motivation for choosing composite materials for structural components. READ MORE

2. Processing and properties of thermoplastic composites containing cellulose nanocrystals or wood-based cellulose fibres
Abstract : Cellulose nanocrystals (CNC) were surface modified with dialkylamines to increase the compatibility between the CNC and the polymeric matrix, and promising results were obtained, with a 300 % stiffness increase when the mixed dispersion was compression moulded on a laboratory scale. The manufacturing process was up-scaled using water-assisted mixing in a twin-screw extruder (TSE) followed by a second compounding step and injection moulding (IM). READ MORE

3. Residual stresses and shape distortion in composite structures
Abstract : High performance composites usually consist of continuous fibres and a thermoset matrix. One well-known example from the aerospace industry is carbon fibre epoxy composites. For that reason the manufacturing processes of thermoset composites are subject to extensive research. READ MORE

4. Prefabricated composite bridges : a study of dry deck joints
Abstract : This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business.

5. Continuous Fibre Reinforced Oxide/Oxide Composites
Abstract : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. READ MORE
